Area Forecast Discussion National Weather Service New York NY 752 AM EDT Tue Sep 28 2021

SYNOPSIS. A cold front passes through the area this afternoon and evening, followed by high pressure. A series of weak cold fronts will move through Wednesday into Thursday. High pressure will then build in and remains through the weekend. A frontal system will approach late Sunday into the beginning of next week.

NEAR TERM /THROUGH TONIGHT/. Forecast is mainly on track and has been updated to capture latest obs and trends. Light showers can be seen on radar just west of our area and will move through northeast NJ and the Lower Hudson Valley over the next hour.

An upper level cut-off low spins over Quebec, as a trough extends down the east coast. At the surface, it's associated low pressure system drags a cold front that is currently analyzed over central New York. This feature will bring showers and thunderstorms to the area throughout the day.

Showers and thunderstorms will be possible as early as the morning hours, as shortwave energy ahead of the front moves through the area. As daytime heating occurs the area should be able to destabilize even more, which will allow for another round of showers and thunderstorms in the afternoon and evening. There is some uncertainty with how much heating will occur due to cloud cover from the earlier showers. This will play a big factor in how today will play out. With dewpoints in the lower 60s at the surface and 500mb temps around -15C, 750-1000 J/kg of MUCAPE can be expected by the afternoon. Given the greater instability later in the day and effective shear values of 25-30 knots, there is a chance of isolated strong to severe thunderstorms developing. SPC has outlined the southern half of our area in a marginal risk. The primary threat will be isolated damaging wind gusts, but given the cold temperatures aloft, 1 inch hail can not be completely ruled out. Locally heavy rainfall is possible in any thunderstorms, but with quick moving storms flash flooding is not a threat. Storm total rainfall is expected to be around a quarter of an inch for most, with locally higher amounts possible.

The whole area should be dry just after midnight tonight. Behind the cold front, winds will be northwesterly as a dry airmass and high pressure build in. Dewpoints will drop into the 40s across the area. The interior should see great conditions for radiational cooling and temperatures should be able to drop into the mid 40s.

SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/. Northerly/Northwesterly flow will continue on Wednesday. A cool day is expected, as temperatures won't make it out of the 60s for most. These highs will be a few degrees below normal for late September.

Late in the day a weak cold front swings through the area, as the aforementioned cut-off low moves further south towards the New England coast. Although moisture is very limited (PWATs .50 to .75 inches), The cold pool aloft combined with surface heating may create enough instability for an isolated light shower or two late Wednesday night.

LONG TERM /THURSDAY THROUGH MONDAY/. Models continue in good agreement with a -1 to -2 STD height 500hpa upper low, and associated deep trough, centered over New England on Thu, and then slowly retreating northeast through Canadian Maritimes this weekend. The evolution of this closed upper low and deep NE troughing is expected to keep Hurricane Sam well out to sea late this week into weekend. The main impacts for the local area will be an increasing threat for rough surf and dangerous rip currents late week into this weekend. Please refer to the National Hurricane Center for the latest forecasts on Sam.

At the surface, a weak front push through the region Thursday as the closed upper low slides through northern New England. Cyclonic flow and pva will bring considerable instability cloud cover and even potential for isolated shower across northern and eastern areas Thursday. Thereafter, Canadian high pressure builds into the region Fri into Sat, lingering into Sunday bringing dry and early fall like weather. Highs will generally be in the 60s to around 70, with lows in the 40s and 50s.

As the closed low lifts N/NE of the area this weekend, models coming into a bit better agreement with development of broad troughing over the north Central US, with a mid week SW US upper low shearing towards the region in a flattening upper flow late weekend/early next week. This will have a frontal system approaching the eastern US Sunday into early next week, but uncertainty on how much progress eastward it makes with confluent upper flow and Canadian high pressure still nosing into the NE US. This system would bring the next threat for rain early next week, but predictability low at this time.

AVIATION /12Z TUESDAY THROUGH SATURDAY/. A cold front approaches this morning and moves through the terminals this afternoon into evening. High pressure builds towards the region tonight.

VFR, outside of shra/tsra. Isolated showers and tsra this am, then scattered showers and thunderstorms expected between 16z and 24z.

SW winds 8 to 12 kt early this morning, veering west through morning push. W/WNW winds this afternoon, becoming NW this evening with frontal passage. NW winds 8-12 kt with occasional gusts to 20 kt tonight.

. NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty .

Isolated shra and tsra btwn 13 and 16z. Scattered shra and tsra and MVFR cigs btwn 16z and 24z. Winds will hover between 300 and 320 mag this afternoon, becoming definitively right of 310 mag during eve push.

OUTLOOK FOR 12Z WEDNESDAY THROUGH SATURDAY. Wednesday-Thursday. VFR. NW winds. Gusts 15 to 20 kt on Wed. Isolated showers east of the NYC metro terminals Wednesday night and Thursday. Friday through Saturday. VFR.

MARINE. A SCA for the ocean waters remains in effect through 2 PM for 5 foot waves. Waves should fall below SCA criteria after this time. Occasional northerly wind gusts up to 25 knots are possible late tonight after the passage of the cold front over the ocean waters.

Winds are expected to remain below SCA criteria (NW gusts to 20 kt) with a series of weak cold fronts moving through the waters Wed thru Thu, and then diminishing further Friday into the weekend as high pressure building over the waters.

Waves are expected to be sub-sca through the remainder of the week, but energetic long period swells from Hurricane Sam will begin to affect the waters Friday and continuing to build into the weekend.

HYDROLOGY. No hydrologic impacts are expected through next Saturday.

TIDES/COASTAL FLOODING. For today, despite a developing offshore flow, a high risk of rip currents is likely with 2-ft long period ESE swells and residual 4-5 ft southerly wind waves.

For Wednesday, an offshore flow continues. Any residual waves diminish to 2-4 ft and will come out of the northeast, which is not a favorable direction. However, 1 ft waves with a long period (13 sec) out of the SE are expected, leading to a moderate risk of rip currents.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . High Rip Current Risk through this evening for NYZ075-080-081- 178-179. NJ . None. MARINE . Small Craft Advisory until 2 PM EDT this afternoon for ANZ350- 353-355.
